| titleOfInvention | 6-epithioethyl-3-oxatricyclo(3.2.1.02,4)octane and production thereof |
| abstract | NEW MATERIAL:A compound expressed by formula I. n USE: A raw material monomer for heat-resistant plastics and optical plastics. Since the polymer of the aforementioned compound has a bicyclo[2.2.1]heptane skeleton and contains sulfur, the polymer is amorphous with a high glass transition temperature and capable of exhibiting a high refractive index and low dispersibility. n PREPARATION: 6-Epoxyethyl-3-oxatricyclo[3.2.1.0 2 , 4 ]octane expressed by formula II is reacted with a thiocyanate expressed by the formula M(SCN) n (M is metallic ion, NH 4 or primary to quaternary ammonium ion having 1-4C alkyl; n is 1 or 2) and/or a thiourea expressed by the formula (R 2 N) 2 C=S (R is H, 1-10C alkyl or aryl) in a solvent such as THF or in the absence thereof at 0-100°C to afford the objective compound expressed by formula I. n COPYRIGHT: (C)1991,JPO&Japio |
